Hivemind increases your honey yield by helping you get to your sites exactly on time. You currently lose 2.36 fortnights of peak production per year (3 weeks + 6 x 2 days). With 110 hives producing 15 lb/fortnight each, you're producing a total of TOTALWEIGHT lb per fortnight.
This is a loss of TOTALWEIGHT x 0.00 = 260 lb/year for each apiary. Since the price of honey is $3.30/lb, your loss evaluates to 260 x $3.30 = $11,682. That's your annual production loss due to timing alone.
Incidental expenses would be around $2,100 assuming 3 unnecessary visits (8 man-hours per trip x $50/hour + $300 fuel @ $67/hour of travel).
Our calculation didn't even include swarm or theft prevention (perhaps $300 per lost hive).
Not to mention peace of mind, better route planning and better apiary management.
